In winter, the material inside the exhaust gas spray absorption tower freezes
Thread Content
In the exhaust gas spray absorption towers, the presence of liquid alkali makes it easy for them to freeze in the northern regions during winter. Since some of these towers are made of RPP, and the overflow pipelines are also made of PP, there are ways to solve this problem without having to perform any welding work on site. Hot water heating was considered as a solution, but the heating pipes are too thick to bend easily without welding, while thinner pipes are prone to clogging. Using steam poses the risk of damaging the PP and RPP materials. I hope someone experienced can help find a solution. Thank you! ! !
How is electric heat tracing for insulation? It’s worth giving it a try
Steam tracing can be applied to the external part of the spray pipe tower; it should be possible to increase the temperature of the medium inside the spray pipes! ! !
I have an idea; I’m not sure if it’s feasible, but it involves using hot water mixed with lye to create a solution for transportation.
By keeping the circulation pump running, it won’t freeze
